I have a neoprene neck seal and latex wrist seals and have no complaints. The same would probably be true for any other combination though.

That seems a bit harsh. he's only trying to understand how things work; not telling everybody who replies that they're wrong.

"Linearity" in this context describes the way that the cell output varies with respect to its input and specifically "how close is it to a line of constant gradient".

Current limiting is an...

A lot of the content you linked seemed to be discussing the idea that the calibration constants could somehow become lost or corrupted without anything else in the software being damaged.

Although...

The underlined part is incorrect as 0.02 bars oxygen could also give essentially 0.000 Volts. Since with two known measurements you can calculate both the gain and DC offset there's no reason not to...

To be honest, I'm still not getting it.

How is knowing that a cell is reading 500mV instead of the exact same thing displayed as 1.2 bars going to help you detect current limiting? The problem is...

As far as I'm aware, PO2 P is calculated from the voltage reading V using the simple relationship

P = a + bV

Where the a and b coefficients are calculated during calibration at two known values...

I don't want to sound like a duffer, but what do you mean by "mv"? The voltage reading in millivolts across the load resistor?

Clearly, the less nitrogen the better, but since the gas is being treated as the worst case (air) anyway, it doesn't seem to make any difference (within the bounds of the MOD) how much there actually...

Just do it in a pool, without any scuba equipment, holding your breath. When you start feeling pressure on your ears blow into your nose until it goes away. You don't need to worry about looking for...

The difference is of course measurable - my aqualung legends have failed the en250 test on an Ansti machine allegedly due to one or both of the adapters or long hose (they've also passed in the same...

Just go to a pool and swim towards the bottom. By the time you reach two metres you should be feeling some pressure in your ears at which point you should pinch your nose and blow into it.

Your...

I think that they pretty much all do. However, very much like the theoretical loss associated with a long hose, it doesn't seem to make any difference in practice.

I don't know which brand they are - ESM most likely.

I only use them for strain relief on the LP hoses because I didn't much like the look of the sharp bends but whilst you're actually in the...

I have little 90° adapters on mine.

Been busy adding support for cell monitoring and boosting the UI a little.

Here's what the dive page looks like these days:

And thé plan...

I've never heard it called anything except the rather unimaginative Lac d'Annecy.

The conservatives will no-doubt fight it that way, centering their campaign around "get brexit done" whilst everybody else divides their vote by squabbling about social inequality and carefully...

Basically agree, but only because I think it's the best, or perhaps only, way to cancel the whole thing.

Except.

1/ Why would the Conservatives do that? They might lose.
2/ Why would Labour do...

So, the prime minister is dead in a ditch, having died rather than done. Yet he's pretty much bound to end up with more "likes" (aka votes) than the all other parties put together.

What a sorry...

A little bit bored, I just worked out that around 1.5 million people have "left the voting pool" since the referendum presumably to be replaced by roughly the same number, if not slightly more.

So...

You can't restow; checking that you can deploy should have been easy but is made difficult.

Brilliant

An MP who backs the deal has basically nothing to lose; one who fights it really has nothing to win.
